The halictine genus Sudila (Cameron, 1898), mainly characterized by the male gigantism, is reinterpreted as a subgenus of Lasiogloss~un Curtis with 6 species: bidentatum, alphenum, aulacophorum, knndiense (all Sri Lanka, males of 2 last species are first described), jacobsoni (Java), and paralphenum sp. nov. (S. India), mainly characterized by singular metepisternal tubercle (absent in paralphenum) and well dentate male inner tibia1 spur (‘jacobsoni, male unknown), all confined to the mountains…
